GAS-FURNACE..

SPECIFICATION forming part of Leners Patent No. 365,950, dated July. s, 1887.

(N c model.)

To all whom it may concern-.-

Be it known that I, JOHN H. TAYLOR, a citizen of the United States, residing at Beaver' Falls,in the county ofBeaver and State ofPenn- Sylvania, have invented certain new and useful Improvements in Gas-Furnaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metallurgical gas and air furnaces, and among the objects of the invention is a reduction of the cost of manu-A facture, a simpliiication and reduction ofthe number of parts composing the same, and the provision of a furnace that is light, portable, and effective.

Vith these general objects in View my invention consists in certain featuresv of construction, hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 'is a vertical section and perspective of a-furnace constructed in accordance with my invention; and Figs. 2, 3, and 4 are details in perspective, hereinafter described. Fig. 5 isa modification.

Like letters of reference indicate like parts in all the figures of the drawings.

A represents in this instance a rectangular combustion-chamber or furnace of any desired construction, and mounted upon suitable legs or standards, A. Cement or other suitable noncombustible material, B, extends entirely or partly around theretort, so as to form one or more of its inner walls.

Mounted at one side ol the furnace or com bustion-chamber, upon suitable legs or standards, A, are the air and gas receiving chambers I K. These chambers are formed by the novel arrangement and combining of peculiarly-shaped plates or castings, as will be hereinafter fully described.

C represents a plate having formed integral therewith or screwed therein a series of air and gas receiving and discharging tubes, C', each of which is formed with a bell-shaped or iared mouth. These tubes, of which there may be any desired number, extend along the plate at suitable intervals and register with burnerholes B in the lining B 'of the furnace. As

shown in Fig. 2, there may be more than one series of tubes instead of the single series shown Vin Fig. l.

ter with and enter into the flared openings of the tubes C.

Back of the nipple plate D, and secured thereto by means of down ward] y andl upwardly extending ilanges E E2, is the gasreceiving chamber plate or casting E, the chamber K thus formed being supplied with gas by means of a supplypipe, F, the supply being regulated by means of an ordinary stop-cock or valve, F.

Arranged between the plates C and D, under the tubes C', is a spacing plate or casting, G,formed with outwardly-extending securingflanges G', through which and the plates C and D and the iiange E2 are passed securing-bolts G2. The plate() is provided,near its top,with a groove, C", into which one edge of the flanged covering II enters. The remaining three edges of the covering is formed with downwardly-extending flanges H', which take over the upper edges `of the nipple-plate D and the ange E2 of the chamber-casting E. The covering His provided with a supplemental cham ber, H2, which communicates with the airchamber I, to which air is suppliedby an air supply pipe, J, the supply being regulated by a stop-cock or valve, J.

Fig. 1 illustrates what may be termed a stationary furnace,77 and the details of construction in what may be termed a burner. In Fig. 5 I have illustrated the burner detached from the furnace; or, in other words, a burner which is adapted to be connected to any ordinary furnace. In this modification the gas-chamber K consists of a single casting, and is bound against the ni pple-plate, which constitutes one wall of the mixing'chamber, in which are the tubes G, the dotted lines J representing the air-supply pipe. The burnen hole plate C constitutes the third casting of the burner, and the three are bound together by the bolts G2, as shown. It is apparent that by thisl modied construction one or more burners may be applied to -a furnace, as desired, and each being provided with an air and gas supply-valve having suitable cut-offs, one

or more of said burners maybe simultaneously the thorough admixture of air and gas and its" passage through the tubes C' before reaching the place of ignition.

From the above descriptionv the operation is at once apparent, in that the air and gas being admitted through their respective pipes J and F yinto their respective distributing-chambers I and K the two elements will take the course indicated by the arrows into the tubes C', where they are commingled and discharged at the Openings B in the lining B, at which point the combustion occurs.

It will be seen that each of the plates may be easily castand assembled Wit-houtfitti ng, and held in position by means of securing bolts or rivets placed at suitable points, so that worn or warped parts may be replaced when neces- 'sarv.

A large number of small articles-such as chains, links, and various blanks requiring welding-are placed in thefurnace A and subjected to the heat of the iiameissuing from the burners B', and by replacing such as are with-I drawn by additional articles a continuous 0peration of heating and welding may be carried on.

Having thus fully described my invent-ion and its Operation, what I claim, and desire to secure by Letters Patent, is-

l. In a furnace of the class described, the

. combination of the plate @,having tubes C,and

plate D, having nipple D', a space-p1ate,'G, interposed between said plates and provided with securing-flanges, with the tlanged casting with the lining B, perforated, as at B, to regi ister with the tubes C', substantially as specitied.

3. In a furnace of the class described, the combination of the plate C, bottom plate, G, space-plate D, casting E, and of the covering H, formed with the supplemental chamber H2, said plates being arranged and combined to form air and gas chambers, substantially as and for the purpose specified.

4. In a furnace of the class described, the combination of the covering H, provided with thepipe and valve J J', the casting E, provided with the pipe and valve F F, with the grooved plate C, provided with tubes, the nipple-plate D,and the spaceplate G,substantially as specified.

5. In a furnace ofthe class described,aburner consisting of three castings,forming, when arranged together as described, two chambers, the outer wall of one of the chambers being provided with burner-holes and mixed air and gas conducting tubes, and thc intermediate wall of the two chambers being provided with gas-nipples arranged to register with the tubes, the whole being bound together in operative position, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
